According to Al Jazeera, U.S. Senators Elizabeth Warren and Chris Coons sent a letter to the Trump administration on Wednesday demanding the preservation of records related to dealings with NVIDIA, suspected AI chip transshipments, and the investigation and handling of Megaspeed. This includes communications between executives and government officials, export control decisions, and case referral materials. The two lawmakers requested that the administration confirm in writing by November 17th that the White House, the Department of Commerce, and relevant offices in the Department of State have issued document preservation directives, and that a briefing be provided to Congress. The above represents the lawmakers' oversight demands and concerns over potential risks, and does not imply that the related allegations have been established, nor does it mean the administration has completed the preservation as requested.
